Closing the GAP between polarity and vesicle transport

Cell. 2006 May 5;125(3):419-21. doi: 10.1016/j.cell.2006.04.011.

Abstract

How are tight junctions maintained? In this issue of Cell, Wells et al. (2006) provide intriguing evidence for a new pathway that links polarity proteins and vesicle transport to the maintenance of tight junctions, through the control of Cdc42 by Rich1, a GTPase-activating protein.
